This is used to type-erase a node. It’s public because the macro needs to use this, but there should be no reason anyone should manually implement this.

Required Methods

fn into_any(self: Box<Self>) -> Box<dyn Any>

Upcast to dyn Any to get its more-specific downcast capabilities

fn as_any(&self) -> &dyn Any

Primarily used for internal checks

fn eval(&mut self) -> Result<HashMap<DataLabel, Arc<dyn Any + Send + Sync>>>

Evaluates the node. Returns a map of prior outputs

fn eval_strategy(&self) -> EvalStrategy

fn reeval_rule(&self) -> ReevaluationRule

fn replace_output( &mut self, key: &DataLabel, output: Arc<dyn Any + Send + Sync>, ) -> Result<Option<Arc<dyn Any + Send + Sync>>>

Set the outputs and return any existing outputs.

fn flow_data( &mut self, parent: &mut Box<dyn AnyNode>, output: DataLabel, input: DataLabel, ) -> Result<(), Error>

This a a core part of the plumbing of this crate - take the outputs of a parent node and use them to set the inputs of a child node.

fn inputs_mut( &mut self, ) -> &mut HashMap<DataLabel, (Arc<dyn Any + Send + Sync>, ReevaluationRule)>

Used to support [Self::flow_data]

fn outputs_mut(&mut self) -> &mut HashMap<DataLabel, Arc<dyn Any + Send + Sync>>

Used to support [Self::flow_data]

fn input_reftype(&self, name: &DataLabel) -> Option<RefType>

Look of the reftype of a particular input

fn set_input_changed(&mut self, val: bool)

Used to indicate that an input has been modified from a previous run.

fn input_changed(&self) -> bool

See [Self::set_input_changed]
